RoR画像タグが見つからない画像

Question

「app/assets/images/wholesale_analysis.png」のようなアセットパイプラインに画像があります。私のテンプレートでは、このタグは<%= image_tag("wholesale_analysis.png") %>ですが、画像が見つかりません。イメージタグに 'alt：'を指定しても、イメージではなくイメージタグのテキストが返されます。イメージタグはレイアウトでは機能しますが、テンプレートでは機能しません。何が起こっている？ wholesale_analysis.pngまたはwholesaleanalysis.png と変更：レールコンソールの結果@Kamil

Answer 1

なりましょう...私のファイルの名前は.html.erbではなく.htmlに変更されました。すべてが今働きます！ご意見ありがとうございました。

Answer 2

はのように、 "卸売" や "analysis.png" 間のファイル名のスペースを削除します同様にあなたのイメージタグは：

<%= image_tag("wholesale_analysis.png") %> 

Answer 3

私は、彼らは、CSSやJSファイルのようにプリコンパイルされるべきではない、あなたの公開/ direcotryに画像を置くために助言します。 あなたが本当にあなたの資産にそれらを持っているしたい場合は、試してみてください：<%= image_tag("/assets/wholesale_analysis.png") %>

Answer 4

@Xenedra資産/フォルダ内の画像を配置し、タグが、私は私の問題を修正し

<%= image_tag("wholesale_analysis.png") %>
